War game movement mechanic

I am drafting out a rough sketch for a war game I have had in mind for sometime. It will play vaguely similiar to titan, although much simpler and quicker. The board will be comprised of 6 differing terrain types, with each terrain type generating a different type of "energy" (or magic/ mana). For simplicities sake, I'm going to have 3 different tiers of summonable creatures available per terrain type. In total, there will be 18 different "units" which can be combined to form an army. The board will be hex, with free movement of armies. I'm having a lot of trouble brainstorming movement methods for armies. I'd like to avoid using roll and move.

The current system I am pondering is this - each player will have a variable number of action points to spend each turn. 1AP = 1 point of movement or it can be used to summon additional creatures to the battlefield. The number of available action points would be determined by a set of cards each player has... maybe 3,4,5,6 and a *special* card. At the start of a turn, the player choose a card and it yields that many AP for that turn. Then, the card goes into into a used pile where it remains unable to be used again until the player picks the special card. The special card awards no AP, but resets the deck allowing anything to be used. I was also considering that on choosing this option a player would also gain VP through the number the of towers they control. (Towers will be one of the VP/win mechanisms) Effectively you would forfeit your turn, reset your available AP cards, and gain VPs on choosing the "special" action.

Personally, I think that your movement system IS simple. I don't see anything complicated about playing a card that says 4 on your turn, and then spending the 4 either moving or summoning. In fact, I would say that anyone who can understand how to roll a die to determine movement should be able to understand this basic concept. If not, maybe they should play another game... though if they don't understand roll die, move guy... well I don't even know what they should play! Haha.

That sounds simple enough, requires strategy of knowing how best and when to allocate. I would give this game a try right now as it sounds interesting. Give this a try and see how it plays, it's not like you are carving the rules into stone.

The nice thing about cars is they can hold allot of info. So you can make the gameplay a LITTLE more complex while retaining the game's simplicity of play. By this, I simply mean that if the card tells you what to do, then it doesn't feel too complex.

Keeping this in mind, would you consider players holding a small hand of, say 3 to 5 cards? Instead of simply having a number of AP on them, each card could have a number of AP, a number of Summons, and, maybe a combat modifier. Each card could, all things considered, be just as good as the next so it's up to the player to pick the right cards to play given the situation at hand.
